PUMPING MEANS Filed April 13, 1927 2 Sheecs-Sheet 2 Patented Dec. 5,`1933 UNETED STATES PATENT OFFICE 12 Claims.

My invention relates to pumping means generally and particularly topumping means which are automatically controlled to retard or to startor to stop a pump means to keep or to maintain a certain quantity ofiiuid in a receptacle or to supply a certain quantity of fluid accordingto certain needs.

The main object of my invention is to provide a pumping means which issimple and inexpensive in structure, which is easily installed, which iseconomical and efficient in operation, which is automatic in operationso that the same requires very little or no attention, which can beoperated either by mechanical means or by a fluidic means or by acombination of both of them, and which can be operated either by aneasily available sourceof power or by a source or power which isotherwise lost or of no further use for other purposes or after it hasperformed its original function. Other objects will appear, or becomeapparent or obvious, or will suggest themselves, during the descriptionof the particular apparatuses shown in the accompanying drawings,

In many instances it is quite desirable to keep liquid at a certainheight or level in a receptacle or tank or can from which the liquid istaken either regularly or intermittently or periodically and either inan even orin an uneven flow, It 30, is also quite desirable that themeans, which keeps this level constant, be operated or operable atminimum cost and that such means operate as near automatically aspossible so that very little or no attention is required for them.

In auto-vehicles, or boats, or other apparatus having a power plant, orindividual power' plants, io instance, a receptacle may supply gasoleneto a carburetor, or a receptacle may supply water to a boiler or to aradiator, or a receptacle may sup- 40 ply air to a burner or to anotherelement to retain the same under a certain pressure or for otherpurposes, or a receptacle may supply other iiuid for other purposes. Insuch cases as well as in similar ones, it is quite desirable that thequantity oi duid taken from the receptacle be replaced in the receptaclein the same ratio or proportion in which it is taken from it. It is alsoquite desirable that the means which so replaces the iiuid be as nearautomatic in operation as is possible so that the entire means needsvery little or no attention and operates at a minimum cost.

In auto-vehicles as well as in many other instances, there are varioussources of power which have served their intended purpose and are going(Cl. 10S-23) to waste or are lost or perform no further function. In theexhaust of gasolene or gas or steam or similar engines, the flow of theintake in gasolene or gas engines, the flow of air from a cooling fan,the moving of the vehicle or of parts .B0 thereof, as well as many othersources of power associated directly or indirectly with a power plant orother apparatus having features as described above, many sources ofpower are easily available for pumping purposes and the use of thesesources of power does not detract anything from or in any mannerdiminish or decrease the eiiiciency of the apparatus or part from whichthese sources are derived since their original and intended usefulnesshas been attained and accomplished and whatever power is still residingtherein-may just as well be utilized for pumping purposes and is usedfor such `purposes in the present invention and thereby operate pumpingmeans without materially increasing the cost of operation of theoriginal apparatus and in many instances practically without cost forthe operation thereof.

In order to illustrate my invention, I have shown in the accompanyingdrawings, by way of example, two devices each having pump means and thenecessary or convenient means associated with or associable with thepump means, and one individual pump which can be used in connection withvarious elements of various apparatus or devices; all of the devicesshown embody features of my invention. I am aware, however, that myinvention can be embodied in other devices or in other apparatuses or inother combinations than those shown.

Fig. 6 is a section taken in a vertical plane similar to Fig, 5 but atright angles thereto and shows the relations between the operating shaftand the crank means and the connecting rod and the plunger and the Valvemeans and the supporting means more clearly.

' Fig. 7 is a general perspective view of a device embodying features ofymy invention and shows a rotary pump jointed or movable on the cover ofa receptacle; the pump cylinder being above the receptacle and theentire pump means being moved toward and away from an abutment anddevice rbore 11 for the pump plunger 12 and the bore 13 to form areceptacle within the receptacle A to retain a certain quantity of thefluid handled by the pump in the receptacle or ybore 13 and thereby keepthe pump primed at all times even when the fluid substance has all beentaken out of the receptacle A. The boss 14 is cast onto the bottom ofthe'receptacle A for purposes appearing presently and the boss 15 iscast onto the side of the receptacle A to receive the pipe or tube 16which conveys fluid from the receptacle A to the carburetor B. In thepresent instance, the fluid in the receptacle A is assumed to begasoline and the carburetor B is assumed to be adapted to effect theproper mixing or other function to adapt the gasoline to a usefulfunction.

The bore 11 has the valve seat 17 at the bottom thereof and the bore 13has the valve seat 18 at the bottom thereof; both valve seats being incommunication with each other through the opening or hole or passage way19. The ball 20 rests on the valve seat 17 and the ball 21 rests on thevalve seat 18; 4both balls forming valves and being free to move 01T ofthe seat thereof and being held onto the seat thereof by their ownweight due to gravity.

The hole 22 is in communication with the hole 19 and with the pipe 23which leads to the i supply tank C and is threaded into the boss 14.

The cover D, a casting in the present instance, closes the top of thereceptacle A and has the ears 24 extending upwardly therefrom and alsohas the abutment 25 and the hole 26 for purposes appearing presently.

The pump housing E, a. casting in the present instance, has the ears 27extending between the ears 24; each of the ears 24 and 27 forming a pairand having the pinv 28 extending through it. This arrangementy forms aswivel or pivot joint so that the housing can be swiveled on the coverfor purposes appearing presently.

The pump operating shaft F has the bearing portion 29 journaled in theboss 3) of the housing the eccentric or crank portion 31 for the connecting rod 32, the bearing portion 33 journaled in the boss 34 of thehousing E, and the portion 35 to which the wheel G is fastened.

The wheel G, a casting in the present instance, has the `rim Scand thevanes 37 similar to the vanes in a fan or in a windmill and the hub 38to support the wheel on the portion 35 of the shaft li.

The plunger 12 extends into the bore 11 and the upper end thereof hasthe slot 40. The connecting rod 32 has the eye 41 fitting to theeccentric pcrtion 31 of the shaft F and the eye 42 extending into theslot 4). The pin 43 extends through the plunger 12 and through the eye42 to form a jointed connection between the connecting rod 32 and theplunger 39.

The housing E, the shaft F and the wheel G thereon, and the connectingrod 32 forni an articulate pump operating means with one end pivotallyfixed and theA other end free to-move or swivel on this pivot.

The shaft 44, journaled in any suitable manner, has the belt wheel 45with the belt 46 running thereon and also has the fan wheel H fastenedthereon. Ths structure represents a power means. Y

The float I has the arm 47 extending to and secured to the arm 48extending from the housing E. vThis structure represents a pumpingcontrol means.

As to the operation of this particular device; starting the descriptionwith the elements in the positions shown in Figs. 1, 2 and 3:-

When the shaft 44 is rotating, either rotated by the belt 46 or movingthe same, the fan 37 rotates and creates an air current moving orflowing toward the wheel G and through the spaces between the vanesthereof and thereby tends to rotate the same in the manner of a windmilland thereby rotates the shaft F which operates the pump means.

The now moving belt 46 is now in contact with the outer circumferentialsurface of the wheel G and thereby also tends to rotate the shaft F byfrictional contact therewith.

The rotation of the shaft F operates the pump- :Ing mechanism in theusual manner and draws gasolene from the tank C through the pipe 23 anddischarges it into the receptacle A. through the hole 13. This dischargeof gasolene into the #D receptacle causes the level of the gasolene torise in the receptacle and thereby creates a condition which raises thefloat I and thereby swivels the housing E on the pivot pins 28 andthereby moves the wheel G away from the belt 46 and out of Contacttherewith and thereby stops the rotation of `the shaft F by the belt andthereby stops the operation of the pump mechanism oy this source ofpower. Y

When the air current operates or rotates the wheel G, eitherindependently of the belt 46 or in conjunction therewith, after thewheel G is the operation of the wheel and consequently of the pumpmechanism by power created by the air current.

While the carburetor B is taking a certain quantity of gasolene from thereceptacle A through the pipe 16 to maintain the level of the gasclenein the receptacle at a certain height, the pump mechanism is operatedconstantly. When the demand for gasolene by the carburetor decreases,the level of the gasolene in the receptacle risesv and moves the floatupwardly and thereby decreases the operation of the pump mechanism orstops the same entirely as explained above. When the demand for gasoleneby the carburetor'increases above normal, the level of the gasolene inthe receptacle falls and moves the iloat downwardly and thereby releasesthe wheel G from the brake to permit the air current to rotate the wheelG and thereby start the operation of the pump mechanism. A further fallof the level of the gasolene in the receptacle moves the wheel G-iurther and contacts the same on the belt and thereby operates the pumpmechanism in a more positive manner. Consequently, the operation of thepump mechanism is automatic and is controlled by the requirement ordemand of gasolene by the carburetor and the pumping activity iscontrolled by conditions created by pumped substance and can vary fromand to full and aero activity and activities in betwen full and aeroactivities.

Referring now particularly to the device shown in Figs. 4, 5 and 6 ofthe drawings:-

The device shown here is an individual unit pump attachable to, orassociable with, various devices and is operable by a suitable aircurrent or by mechanical means described above or by other suitablemeans.

The cylinder K has the bore 49 with the valve seat 50 and the hole 5i inthe bottom thereof and also has the boss 52 externally threaded toreceive the nut 53 and internally threaded to receive the pipe 54 whichleads to a supply tank. The nut 53 clamps the ilange 55 of the cylinderagainst the member 56 which may constitute the bottom of Va receptacleor other means for supporting the cylinder, The cylinder also has thebore 57 with the valve 58 in the bottom thereof. The hole 59 establishescommunication between the bore 49 and the bore 57. The ball 60 normallyrests on the seat 50 due to gravity and the ball 61 normally rests onthe seat 58 due to gravity. Ears 62 are provided on the upper end of thecylinder.

The housing L has the ears 63 adjacent to the ears 62 and forming pairstherewith with the pivot pins 64 extending through the pairs of ears andalso has the bosses 65 and 66 on the upper end thereof.

The shaft M has the bearing portion 67 journaled in the boss 65 and theeccentric portion 68 and the bearing portion 69 journaled in the boss 66and the brake portion 70 and the portion 71 to which the hub 72 of thewheel N is secured.

The wheel N has the friction element 73 and the vanes 74 similar to awindmill so that the wheel can be operated either by an air current orby mechanical means as described in connectionr with the device shown inFigs. l, 2 and 3.

The abutment 75 extends from one of 'the ears 62 and is xed and has theoblong hole 76 through it; each end of this hole is curved to the sameradius as the brake portion 70 so that this brake portion engages thesecurved ends and forms a brake similar to the brake eiect producedbetween the wheel G and the abutment 25 when the housing L is swiveledon the pins 64.

The connecting rod O has the boss 77 over the eccentric portion 68 andthe boss 78 extending into the slot 79 in the plunger 80 and pivot-allyheld 'therein by the pin 81 extending through the plunger and throughthe boss 78. The plunger rits slidably and operates in the bore 49.

In this instance, the housing L, the rod O, the shaft M, and the wheel Hform an articulate pump operating means pivoted at one end and free tomove at the other end in a manner and .for purposes as the device shownin Fig. l.

The operation of this device is similar to the operation of the devicedescribed above; the wheel N is movable toward and away from a drivingmeans; in this instance, the housing swivels on the cylinder whereas thehousing first described swivels on the cover of the receptacle.

Referring now particularly to the device shown in Fig. 7 of thedrawings- In this device, the rotary pump P is movable bodily on thecover Q which closes the receptacle R and is moved toward and away fromthe wheel S and to and from the abutment 82 by means of the bell crankarm 83 extending from the float T and pivoted on the pin 84 extendingthrough the ears 85 on the cover Q and having the connecting rod 85pivoted to the ears 87 which extend upward from the arm 83 and therebyconstitutes an articulate pump operating means. The rod 85 is threadedinto the pump so that the pump moves laterally as the float rises andfalls in the receptacle. When the pump is so moved by the iioat, thewheel 88 is moved toward and awa* from the wheel 89 as well as towardand away from the abutment 82. The wheel 89 may be operated by anysuitable means and the fan wheel 9G may be mounted on the same shaft asthe wheel 89 or on another shaft.

Either one of the devices shown and described can be operated by asource of power which is easily available and which may have had nofurther utility; the air current used may conveniently be the aircurrent produced by the fan of an auto-vehicle and used after the samehas accomplished its originaliy intended oiice; a belt which drives theian of an auto-vehicle or another device can easily be used to operatethe pump means with practically no cost for power; in fact the .i

belt is brought into better contact with the pulley thereof by the usethereof as a power source for pumping purposes as herein set forth.

Each of the pumping means shown and described has a means forautomatically supplying iiuid as needed at a minimum cost.

I am aware that my invention can be applied to apparatus and devicesother than those shown and described andthat changes may be made and canbe made in thestructure as well as in the arrangement of the elementsshown and described within the scope of the appended claims; therefore,without limiting myself to the precise application of invention as shownand described nor to the precise structure and arrangements of elementsas shown and described.
